Julia's twin brother, Wyatt, passed away in 2010 after a heroic battle from Synovial Cell Sarcoma. Cancer can suck it.
His cancer developed in his jaw, so intensive radiation and chemotherapy left him with half a face of facial hair -- hence "Half-Stache". His facial hair may have left him, but his humor, charisma, and swagger rose to the occassion. Wyatt was legendary, and so was his half-stache.
With funding get slashed, and cancer being trash, come dump your wads of cash into the 7th Half - Stache Bash.
Plus, it's their 40th.
